Opis

The most common tumors in ruminants are lymphoma, leukemia, squamous cell carcinoma, and melanoma. Some of the more common tumors, such as lymphoma and squamous cell carcinoma, are better documented. On the other hand, ocular squamous cell carcinoma manifests as an infiltrating eyelid mass in adult cattle with poor periocular pigmentation. Similarly, juvenile and dermal forms of LBS affect young dairy cows with polyadenomegaly or skin nodules. However, other tumor processes, related to the organ involved in the primary tumor or metastases, are also possible. Histological examination is the microscopic examination of tissues to study the appearance of cells and tissues in order to diagnose tumors such as other diseases. It is an important tool for the diagnosis of cancer. It is therefore the confirmatory examination of tumors. Usually, immunohistochemistry is the most common histological examination. Necropsy can be used to diagnose tumors. It is a post-mortem examination of an animal to determine the cause of death or assess pathological conditions. It is the ultimate diagnostic fate of most experimental animals.
